Q: What is meant by unlocked iPhone7 with carrier AT

Thanks Brian. Can I go and buy iPhone 7 from Apple store and can use any SIM other than the ones mentioned on the Apple site? Because the Apple store representative was not sure about this and also Apple site does not have any option to order "Unlock" iPhone 7 (like it has for 6/6s etc.).

Hi harshavardhanfromcarbondale, Thanks. So you bought iPhone7 from Apple store using full payment option with carrier say AT & T and now you are using the same iPhone7 with SIM card of other carrier?

Hi Harshavardhan - Thanks again. But I wanted to know if it works for other SIMs other than AT&T, Verizon, T-Mobile (the ones mentioned on the apple site). Will it work with other carriers outside US?
